OK. I understand, but all I've done (`3-4 ISPs) have had the configuration done in the modem before the router was put into the flow of things.

As far as I know, the data is saved on the router, behind the router's firewall. If it's only a modem connected to the computer (without a router), then the data is saved in the computer. I could be wrong, of course, but keep in mind that when you set the router you first have to access the router with an URL (address), and after all the data, including the firewall, are set, then one has to save it before exiting the router. Part of the process is assigning both a router and network passwords. If you don't assign a network password on the wireless router, then anybody can park on your driveway (for example), and connect to the Internet via your network

If I disconnect the router from the network, then the modem uses the "network" account in the computer to connect to the ISP, but the computer is wide open to the rest of the net once it connects though the ISP system, so any hacker can access or see your computer. The router shields the network from the net.

That said, I am willing to learn, since it's very possible that I am wrong.

Here's what I know to be true. When Verizon ran the land line business, both in West Virginia and in New England, the PPPoE account name and password were typically stored in the DSL modem. I know one guy that ran his in bridge mode, but that was his own choice. I've been through configuration on several routers. Each one has an admin account with a name and password. This is for router configuration. Wireless routers also have a name and password for wireless access (SSID & Key), but these are not related to the access for the ISP. Once these things are set up, you can remove all the computers from the network and replace them with others and the access to the network will still work, indicating that the account information is not actively being used from any of the computers.

What I suspect is the problem for the OP is that the cable modem is remembering the MAC address of one of the computers and it may be necessary to copy that MAC address into the router.

That is the purpose of pulling power from the cable modem, to clear the previously connected device, I've had occasions where I've had to keep it unplugged for 10 minutes before it would work properly.
